使用Air724模块设计全功能DTU

目前物联网开发中，4G模块的使用方式有几下几种：

  1. MCU连接4G模块，使用串口通讯，MCU通过AT指令控制数据收发；
  2. 4G模块通过USB连接到ARM等系统，通过RNDS或者PPP拨号上网。
  3. 4G模块支持二次开发，直接在模块片上开发应用。

方案1适合各类低配MCU，对系统要求低，但是AT指令解析繁琐，效率低速度慢。
方案2适合带有USB和有运行系统的设备，比如ARM+linux。
方案3只适合支持二次开发的模块，而且一般4G模块受硬件限制，外设或功能受限。

合宙724 cat1模块

接下来将一步一步介绍我们物联网系统的设计思路和架构。我们的物联网基础能力设备预计将设计4G、NB、LORAWAN三种类型，其中4G方案选用了合宙Air724模块，主要是是其支持二次开发，且性价比较高，

从开源的IRTU开始

  • Air724模块底层采用FreeRTOS开发，合宙的开发人员移植了自家的Luat架构，把elua运行在了724上，这样Air724模块应用采用Lua脚本开发。
  • 合宙支持基于Lua开发了一个iRTU程序，功能丰富。我们将在iRTU基础上集成我们自己的功能和对接到我们的平台。
  • 我们的目标是让DTU实现全远程脚本化管理，即使二次开发也不需要写代码、下载固件,大概的功能设计如下：
